FTR, here is the last boot log: https://paste.debian.net/1385224/

I thought asking about CONFIG_DEBUG_INITCALLS was the first thing I did,
but I might misremember. Anyways, you are clearly reaching barebox
proper now, so just forget about all the putc_ll() stuff, you only need
that for the early hangs, which isn't the case for you.

As for why it hangs, I suspect you have CONFIG_ARCH_SOCFPGA_ARRIA10
enabled, despite that SA2 using a Cyclone V.

Can you check if CONFIG_ARCH_SOCFPGA_ARRIA10 is enabled and try again
after disabling it if it is?

Cheers,
Ahmad
